Abstract

ANALISA OPTIMASI DEWATERING DENGAN VARIASI KOAGULAN PADA LUMPUR LIMBAH AKTIF MENGGUNAKAN PLATE AND FRAME FILTER PRESS Dina Elvia Rani’* 21030116060061 Penelitian ini bertujuan untuk mengembangkan skema proses filtrasi untuk analisa tahanan medium filter (Rm), specific resistance to filtration (SRF), kadar air (moisture content) serta yield pada dewatering lumpur limbah. Target yang ingin dicapai berupa optimasi jenis koagulan pada proses dewatering lumpur limbah. Kajian dilakukan pada berbagai variabel diantaranya variabel bebas meliputi variasi koagulan (Tawas 80 gr/lt, 100 gr/lt, 120 gr/lt dan PAC 72 gr/lt, 100 gr/lt, 128 gr/lt) dan variasi tekanan (56 kg/cm 2 , 60 kg/cm 2 , 70 kg/cm 2 ). Sedangkan variabel tetap meliputi volume lumpur, volume pelarut, kecepatan dan lama pengadukan, serta volume filtrat. Percobaan menunjukkan jenis koagulan yang optimum diperoleh yaitu pada koagulan Poly Alumunium Chloride (PAC). Untuk analisa SRF sebesar 6,53E+09 m/kg ; analisa Rm sebesar 6,75E+12 1/m ; analisa kadar air sebesar 69,82% ; analisa yield sebesar 20,68 kg/m 2 h. Kata kunci : filtrasi, lumpur limbah, dewatering ABSTRACT OPTIMIZATION ANALYSIS OF DEWATERING WITH COAGULANT VARIATION ON ACTIVATED SEWAGE SLUDGE USING PLATE AND FRAME FILTER PRESS Dina Elvia Rani’* 21030116060061 This research aims to develop the filtration process scheme for the analysis of resistance associated with the filter medium (Rm), specific resistance to filtration (SRF), moisture content and yield for sewage sludge dewatering. The target to be achieved is optimization the type of coagulant in the sewage sludge dewatering process. The study was conducted on various variables including coagulant various (Tawas 80 gr/lt, 100 gr/lt, 120 gr/lt and PAC 72 gr/lt, 100 gr/lt, 128 gr/lt) and pressure various (56 kg/cm 2 , 60 kg/cm 2 , 70 kg/cm 2 ). The experiment showed that the optimum coagulant of the influence of Poly Alumunium Chloride (PAC) coagulant. Value for analysis of SRF was 6,53E+09 m/kg ; analysis of Rm was 6,75E+12 1/m ; analysis of moisture content was 69,82%; analysis of yield was 20,68 kg/m 2 h. Keyword : filtration, sewage sludge, dewatering
